You are asking netmon to do more work on the fly than he can handle.
803 devices alone is a big smartset, but 803 routers is huge, because we
are talking about every interface on those routers. You are forcing
netmon to re-evaluate the polling cycle for hundreds of nodes, perhaps many
thousands of nodes, in mid-stream. Of course he falls behind. It will be
hard to catch up, though he will eventually.
My advice is to delay this until you can take down all the GUIs and restart
all the daemons, especially netmon, from scratch

Subject: [NV-L] Smartsets in SNMP Configuration (xnmsnmpconf)
Hello Everyone.
NV for UNIX 6.0.2 on AIX 4.3.3.4
This morning I setup a SNMP configuration that used an existing SmartSet.
The SmartSet contains 803 of our remote routers. NV reports many of these
devices as down or unreachable when in fact there is no problem. Upon the
next status poll cycle, a node up event occurs. These devices are routers
that convert the data received from the satellite dish to ethernet packets.
As you know satellites introduce a high latency. Ping responses can be as
high as 800 - 1000 msec.
I wanted to increase the polling interval to 6m (was 5m) and set the route
entries to 100 (was 800) just for these routers. When I add the SmartSet to
the SNMP configuration, netmon becomes so busy that polling falls behind.
If
I try the netmon -y command, the trace file is not updated with "netmon
seed
file loaded successfully". If I attempt to start the netmon trace (netmon
-M
-1), no events are posted to the netmon.trace file, not even the "change
trace mask to 0xffffffff". I occasionally get the "netmon daemon not
responding" or the "SNMP collect daemon not responding" popups. They are
often followed by the "Correlation daemon is now responding".
As soon as I delete the SmartSet from the SNMP Configuration, the
netmon.trace file is updated immediately with "trace mask" or "seed file
reloaded successfully" messages.
Has anyone experienced this problem?
Thanks in advance.
